چکیده مقاله :
بیان مسئله: پروژه های حوزه ساخت اخیراً دوباره کاری ها و تغییرات ناخواسته ی قابل توجهی در مرحله اجرا تجربه کرده اند که تاثیر منفی بر عملکرد پروژه می گذارد. بررسی دوباره کاری ها در حوزه صنعت ساخت و عوامل موثر بر آنها نشان می دهد که بخش قابل توجهی از تغییرات ناخواسته و منازعات ناشی از آن در پروژه ها به دلیل عدم هماهنگی مناسب بین ذینفعان پروژه، ارتباطات ناکارآمد و یا با تاخیر بین طرف های پروژه و شکست در تشریح الزامات تحویل و به طورکلی مدیریت سطح مشترک ضعیف و عدم هماهنگی بین شرکت کنندگان مختلف پروژه می باشد که به صورت مستقیم و یا غیرمستقیم بر عملکرد پروژه تاثیر می گذارند و دوباره کاری ها را ایجاد می کنند. هدف پژوهش: هدف از این پژوهش بررسی نقش بهره گیری از مدیریت سطح مشترک بر کاهش دوباره کاری ها در پروژه های ساخت می باشد ، که برای نیل به این هدف به شناسایی علل اصلی دوباره کاری ها در این پروژه ها پرداخته شده است تا با کمک آنها بتوان تاثیر بهره گیری از مدیریت سطح مشترک بر کاهش دوباره کاری ها و درنتیجه بهبود عملکرد پروژه را مشخص کرد. روش پژوهش: در این مقاله به بررسی تاثیر بکارگیری مدیریت سطح مشترک بر کاهش دوباره کاری های پروژه های ساخت پرداخته شده است, بنابراین ابتدا با مرور مبانی نظری, فرضیه های پژوهش نوشته شد و سپس با استفاده از پرسش نامه, داده ها جمع آوری شد. جامعه آماری پژوهش شامل تمام دست اندرکاران صنعت ساخت ازجمله مجموعه کارفرمایان، مشاوران و پیمانکاران است. از این جامعه آماری, 291 نمونه آماری به روش تصادفی ساده انتخاب شدند. پژوهش حاضر کاربردی و روش پژوهش, توصیفی از نوع پیمایشی بوده که اطلاعات به روش میدانی جمع آوری و برای تحلیل داده ها از آزمون دوجمله ای استفاده شده است. نتیجه گیری: یافته های پژوهش نشان می دهد که شناسایی سطوح مشترک و مدیرت آنها در پروژه های ساخت می تواند با اثرگذاری بر مولفه های اصلی بروز دوباره کاری ها باعث کاهش اتلافات ناشی از آن در حوزه صنعت ساخت شود.
Due to the increase in the complexity and size of construction projects, the significant increase in the stakeholders involved in the project, the increase in the speed of project implementation and the risk variables caused by these factors, the management of construction projects faces significant challenges. . Also, the characteristics of construction projects, poor supervision of the project workshop, construction complexities, the existence of temporary multi-organizational nature, sub-contracts and interdisciplinary contracts in a project cause various interface issues. Also, recent construction projects in Iran have experienced significant rework and unwanted changes during the implementation phase, which has a negative impact on the project's performance. The analysis of the classification of construction rework and the factors affecting them shows that a significant part of the unwanted changes and the resulting conflicts in the projects are due to the lack of proper coordination, inefficient or delayed communication. between the project parties and the failure to explain the delivery requirements and in general poor interface management and lack of coordination between the different participants of the project in the implementation phase, which directly or indirectly affect the performance of the project and rework They create The purpose of this research is to investigate the role of using common interface management in reducing rework in construction projects, which identifies the main causes of rework in construction projects so that with their help, the effect of using interface management on the reduction of redundancies and as a result the improvement of project performance.
